Broken T56, what's this? Last month I picked up a used GTO T56 with about 25000 miles since it was rebuilt. It was shipped UPS and the box was a little beaten up but upon inspection the tranny seemed fine.
A couple of days ago, I was giving it a good power washing to clean it up and as I rolled it onto it's side I heard a little rattle inside. It sounded like a bolt or nut was rattling around in the case. I pulled the slave cylinder off and cracked the front case open and found this little gem. I couldn't see anything that looked broken in the front half of the case, so I put it back together and dropped it off a transmission shop. It'll be a few days before they can tear it apart, but I'd like to have an idea going into it, what this part is.
Can anyone identify this for me?

And here's a couple pics of the inside of the case. I see some similar parts, but not an exact match and nothing here looks broken:

It's the shift rail interlock (Part# 156 on the T56 diagram). Something must have whacked the shift rail violently to break that. It's where the shift fork links all rest/ride on the shift rail. You can see the other half of it in your next-to-last picture at the top, in between the upgraded steel 3/4 fork and the aluminum 1/2 fork behind it.

Also is this the piece that you're referring to? (this would be the good side, broken piece on the opposite side?)
